Psalms 92:15

God sometimes grants prosperity to wicked men in displeasure; yet they flourish but for a moment. Let us seek for ourselves the salvation and grace of the gospel, that being daily anointed by the Holy Spirit, we may behold and share the Redeemer's glory. It is from his grace, by his word and Spirit, that believers receive all the virtue that keeps them alive, and makes them fruitful. Other trees, when old, leave off bearing, but in God's trees the strength of grace does not fail with the strength of nature. The last days of the saints are sometimes their best days, and their last work their best work: perseverance is sure evidence of sincerity. And may every sabbath, while it shows forth the Divine faithfulness, find our souls resting more and more upon the Lord our righteousness.

This mercy to the aged proves the faithfulness of their God, and leads them to shew that the Lord is upright, by their cheerful testimony to his ceaseless goodness. We do not serve a Master who will run back from his promise. Whoever else may defraud us, he never will. Every aged Christian is a letter of commendation to the immutable fidelity of Jehovah. He is my rock, and there is no unrighteousness in him. Here is the psalmist's own seal and sign manual; still was he building upon his God, and still was the Lord a firm foundation for his trust. For shelter, for defence, for indwelling, for foundation, God is our rock; hitherto he has been to us all that he said he would be, and we may be doubly sure that he will abide the same even unto the end. He has tried us, but he has never allowed us to be tempted above what we are able to bear: he has delayed our reward, but he has never been unrighteous to forget our work of faith and labour of love. He is a friend without fault, a helper without fail. Whatever he may do with us, he is always in the right; his dispensations have no flaw in them, no, not the most minute. He is true and righteous altogether, and so we weave the end of the psalm with its beginning, and make a coronet of it, for the head of our Beloved. It is a good thing to sing praises unto the Lord, for "he is my rock, and there is no unrighteousness in him."
